I then downloaded the Bit Defender AV app for andriod/kindle and performed a scan. The scan came back clean.

However when I downladed the Bit defender App I was expecting it to download some virus definitions (like you'd expect, if you were on your PC), but it didn't. I thought that was a little strange.

Once I hade scanned the device. I turned off the wifi and then turned off the Kindle.

I'm about to factory wipe my Kindle.

What do you reccomend ? Am I being a little paranoid ? (I don't think there is anything wrong with a little healthy paranoia when you're dealing with computer security though).

I've not noticed any unusual activity on my Amazon app account today. (However, that's not really surprising as I've turned off the Kindle. So even if it had been infected it wouldn't have had much of a chance to do anyting yet).

I suspect it's just a scare-ware pop up. Has anyone else seen this, or anyting like this at all on thier tablet devices ?

I'm not qualified to give you a definitive answer. So I give you my opinion.

Kindle's OS is probably based on Android/Linux and would not be affected by malicious code created for a PC. Most PCs run Windows so the people who create viruses tend to focus on code for that platform.

The kindle's storage area is like a USB flash drive (The Firmware/OS would be on a separate partition). While a virus cannot run in the storage area it is unlikely but possible that it could transfer to your PC from there.

When you connect the Kindle to your PC it should show up as a mass storage device. There's no harm in letting your PC's AV scan it.

Can you post a link to the screen shot?

I don't have any AV on my Android devices and have never had any issues.

If you are particularly worried. Restore the Kindle to factory settings. That should wipe any iffy files that you have downloaded as well as your data.

Caveat: I speak from a general background, not current knowledge of Kindle security.

There is relatively little malware capable of directly infecting a Kindle Fire (which AFAIK uses Amazon's own hacked version of Android). The OS is fairly secure against traditional PC viruses, and Amazon's hacks probably won't help compatibility with Android-specific attacks either. BitDefender is hopefully more concerned that basic lockdown settings haven't been compromised, and could get any handful of signatures it needs by transparently downloading them from Mummy without bothering to tell you.

Most malware of the type you describe requires the user to (unknowingly) grant it access permissions by clicking something, which, since you carefully didn't, makes it unlikely that anything cached by your browser ever got activated.

Does the browser have a cache that can be cleared? Other than that, personally I'd just keep an eye on the device for a while, just in case it was compromised and something recurs.

Frankly, the data sucked off and traded around the world as a matter of course by the likes of Amazon, Google, Facebook, et. al. is likely to have compromised your privacy far more.

Since I last posted, I received another message claiming I was infected with another virus.

I got fed up, and wiped my Kindle and started again fresh.

As an aside, I currently have the Bit defender app installed on my device.
Is it wise/possible to run two or more AV apps on the kindle at the same time ?
I know you really shouldn't do this on a win PC, as they tend to conflict.
Does this cause any issues on android ?

Who is this website to make such a claim? They don't look to be a page from a trusted AV provider. To be honest it looks more like a phising attempt. Could the site be compromised? Is it always the same site/domain? It may even just be an aggressive advert. Even if I was on a Windows machine and that message popped up I'd just ignore it and carry on my merry way.

I've just had a quick look on-line and none of the big boys (Symantec, Kaspersky etc.) offer on-line kindle scans. If Kindle was at risk I'm pretty sure they would as they do for PCs. They love to scare you into buy their products after all that is how they make money.

I posted one of the links in my first post.
(I just broke up the link in case that it may have sent someone to a dodgy infected site)
I don't think it would have, I just wouldn't want anyone to get caught out.
